Audio Identifier String Encoding for Multi-Device Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face challenges in enabling interactions between multiple devices when they are not connected to the same network or when a network is unavailable, limiting their ability to perform interactions effectively.
Innovation Solution
A method where a transmitting device detects a media content control command, encodes it into an audio identifier string, and transmits it through sound waves, allowing a receiving device to extract and decode the command to operate on corresponding media content, even without a shared network connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices are connected to the same network for interactions, then interaction reliability is improved, but device complexity and network dependency increase
Solution Approach 1:
The patent uses sound waves as an intermediary medium to transmit control commands between devices. The transmitting device converts control commands into audio signals that can be detected by the receiving device, enabling communication without direct network connectivity. This intermediary approach resolves the contradiction by providing a alternative communication path that maintains interaction reliability while reducing network dependency.
Solution Approach 2:
The patent replaces the electronic/network-based communication system with an acoustic/mechanical system. By substituting network protocols with sound wave transmission, the system eliminates the need for complex network infrastructure while maintaining device interaction capability. This substitution reduces device complexity and network dependency while preserving interaction reliability.
2Loss of information
If network connection is required for device interactions, then data transmission accuracy is improved, but adaptability to different environments deteriorates
Solution Approach 1:
The patent implements a universal communication mechanism that can operate in multiple environments with or without network connectivity. The control command transmission system is designed to function both through network channels and through sound wave transmission, making it adaptable to different environmental conditions. This multi-functionality resolves the contradiction by maintaining data transmission accuracy across diverse environments without requiring constant network connection.
3Adaptability or versatility
If sound waves are used for data transmission, then adaptability to network conditions is improved, but information encoding complexity increases
Solution Approach 1:
The patent extracts only the essential control command information from the original data and encodes it into audio signals. By taking out only the necessary control elements (such as play, pause, volume control) and transmitting them through sound waves, the system achieves network independence while keeping the encoding process relatively simple. This selective extraction approach resolves the contradiction by maintaining adaptability without excessive encoding complexity.

Data Source
AI summary
Systems, devices and methods are provided for multi-device interactions. For example, a transmitting device detects a media content control command input by a user for operation of a first application client, wherein the media content control command includes media content identification; the transmitting device encodes the media content control command into an audio identifier string; and the transmitting device transmits the audio identifier string through first sound waves. A receiving device is configured to detect the first sound waves using a second application client, extract the audio identifier string from the first sound waves, decode the audio identifier string to acquire the media content control command, and operate on first media content corresponding to the media content identification included in the media content control command.
